Comparing values within two vectors

Hello everyone, I have two vectors of different length and I need to iterate through the first one A = randi(25,372,1) and find the corresponding value in vector B = 1:1:25 and return it's index. I need to do this for every single value in vector A (372) What I have so far:

    A = randi(25,372,1)';
    B = (1:1:25)';

    for i = 1:1:372
        ValueA = A(i);
        for j = 1:1:25
            ValueB = (Bj);
            if B(j) == A(i)
               [index, Lib] = intersect(B,A);
            end
        end
    end

Any help will be much appreciated

A = randi(25,372,1);
B=1:25;
[ ~,jj]=ismember(A,B)
